There might not be a single optimal diet for humans, but
health-producing cuisines—especially ones with a reputation for healing
ailments and reversing chronic conditions—typically have a few things in
common.

Elimination of refined sugar, high fructose corn syrup, and other
nutritionally-devoid sweeteners

But regardless of what you put in your mouth, remember that an optimal
diet is one you can sustain—and that doesn’t knock your whole life off
kilter by making you socially, mentally, or emotionally imbalanced. Diet
is only one component of health and should never become the driving
force in your life.
